I am. I got pregnant during my sophomore year in undergrad but managed to graduate only one semester late (took a semester off while the baby was born so I could breastfeed and we could bond. I also don't think I would have been able to function in school during the newborn stage with the no sleep and all). It's all about time management. If you have any time between classes, do not use it for lunchtime, use it for studying, as you will not be able to do so while your child is home unless they are asleep. Also allow for plenty of family time. For me that means no studying after school and none during weekends (I have pulled a lot of all nighters so get be prepared for that as well). Overall it's definitely doable, you'll just have to work a bit harder than the others, but it is all worth it.
Congrats.
